I'm so stuck on this question, feeling a bit useless. I don't recognise num?

Trying to figure out this question but typing help(num) obviously came out invalid and then i got stuck with a "logout"

Feeling like i'm never going to get this.

Complete the for loop below:


>>> my_list = [1, 2, 3, 4]
>>>  num  my_list:
...     print(num)
1
2
3
4

Hi Calvin!

So, it's helpful here to remember that you're creating a for loop, which follows the basic syntax:

y = [ 1, 2, 3, 4 ] # Your list

for x in y:
    print x

This basically says for every item(x) in the list(y), process the code within the loop until you reach the end of the list - in the example, you're printing to the screen using print x.

So in the case of the question in the quiz, num is simply what you are assigning to represent each item in the list.

it could easily be...

barrel = [ "granny smith", "delicious", "mcintosh"] # Your list

for apples in barrel:
    print apples

I hope that helps to clarify things a bit!
